LI-7810 CH4/CO2/H2O Trace Gas Analyzer
The LI-7810 CH4/CO2/H2O Trace Gas Analyzer offers high performance methane measurements in a surprisingly rugged and portable design. Precise and stable measurements are the result of a combination of several patented technologies integrated with Optical Feedback-Cavity Enhanced Absorption Spectroscopy (OF-CEAS).
- Provides the precision of a benchtop analyzer in a portable, weather-resistant case
- Operates on hot-swappable, long-lasting batteries
- Has an available backpack harness
- CH4 Precision (1σ): 0.60 ppb at 2 ppm with 1 second averaging
- Maximum Drift: < 1 ppb per 24-hour period
The LI-7820 N2O/H2O Trace Gas Analyzer is a low power, rugged addition to survey and long-term systems. This highly precise and user-friendly N2O analyzer pairs easily with the LI-7810 for added CO2 and CH4 measurements or the LI-870 for added CO2 measurements.
- Requires low power and uses hot-swappable, long-lasting batteries
- Works with SoilFluxPro™ Software for easy data management and analysis
- Has an available backpack harness
- N2O Precision (1σ): 0.40 ppb with 1 second averaging at 330 ppb
LI-870 CO2/H2O Analyzer
Get rapid, repeatable measurements of soil CO2 flux. The LI-870 CO2/H2O Analyzer is designed for survey measurements with the Smart Chamber. This portable, lightweight analyzer is capable of a full day of survey measurements, and power is supplied directly from the Smart Chamber.
- Small and lightweight for a full day of survey measurements.
- Low power consumption: 20 hours field use (2 batteries; 10 hours per battery with 2 minutes per collar active time and 20 collars total per hour).
- Low maintenance analyzer with a user-serviceable optical bench
- Accuracy: Within 1.5% of reading
- Measurement range: 0 to 20,000 ppm
If you are looking for a laser-based solution for soil CO2 flux survey measurements, the LI-7815 CO2/H2O Trace Gas Analyzer is available. Ask us which solution is a good fit for your research.
Additional Gas Measurement Options
A third-party gas analyzer can be used with the Smart Chamber. Data from both the analyzer and the Smart Chamber are collected simultaneously. Then both datasets can be merged with SoilFluxPro Software to determine the fluxes.
Processing measurements in your lab? The Trace Gas Sampling Kit is a simple add-on to the Smart Chamber that lets you work without a gas analyzer. Simply collect gas samples from sampling tubes and use the Smart Chamber for time, location, auxiliary, and other data.
